Overview

There is no well established classification for basal cell carcinoma, however there are few clinical variants which are nodular, cystic, sclerodermiform, infiltrated, micronodular, superficial, and pigment basal cell carcinoma and fibroepithelioma of Pinkus.

Basal Cell Carcinoma Classification

Clinical Variants Description
Nodular BCC Comprises about 60-80% of cases; most commonly found on the skin of the head; clinically: elevated, exophytic pearl-shaped nodules with telangiectasias on the surface and periphery; histologically: nest-like infiltration from basaloid cells
Cystic BCC ≥ 1 cystic node with different sizes located peripherally to the centrally placed tumor nests
Sclerodermiform (morpheiform) BCC The tumor cells are surrounded by fibrotic stroma; clinically: infiltrated plaque with a slightly shining surface and not well-defined borders; immunochemistry: expression of smooth muscle alpha-actin
Infiltrated BCC Most common found on the upper part of the trunk or face; clinically: whitish, compact, not well-defined plaque; histologically: thin, nest-like bundles of basaloid cells infiltrating in the dermal collagenous fibers
Micronodular BCC Most commonly found on the skin of the back; clinically: may be flat or elevated; yellow-whitish color when flat, clear outlines and thick at palpation; histologically: small rounded nodules of basaloid cells and minimal palisading
Superficial BCC Comprises about 10-30% of cases; clinically: erythematous squamous plaque with clear borders, pearl-shape edge, superficial erosion, without tendencies for invasive growth; histologically: nests of basaloid cells located subepidermally, connection with the basal layer of the epidermis and no infiltration of tumor cells in the reticular dermis
Pigment BCC The color varies from dark brown to black; clinically: nodular, micronodular, multifocal, superficial; histologically: nests of basaloid cells, melanocytes and melanophages, moderate inflammatory infiltrate
Fibroepithelioma of Pinkus Most commonly on the skin of the back; affects women especially; clinically: elevated pink or erythematous nodules; histologically: trabecular, elongated, and branched thin strands of basaloid cells
